OSIRIS-REx outbound orbit to asteroid Bennu, including an Earth-gravity assist approximately one year after launch. The gravity assist will adjust the spacecraft’s orbit, putting it in the same inclination as the orbit of Bennu.
The Origins Spectral Interpretation Resource Identification Security - Regolith Explorer spacecraft will travel to a near-Earth asteroid, called Bennu (formerly 1999 RQ36), and bring at least a 2.1-ounce sample back to Earth for study. The mission will help scientists investigate how planets formed and how life began, as well as improve our understanding of asteroids that could impact Earth.
OSIRIS-REx launched on Sept. 8, 2016, at 7:05 p.m. EDT. As planned, the spacecraft will reach its target asteroid in 2018 and return a sample to Earth in 2023. These animations depict the journey of OSIRIS-REx to Bennu and back, including the complex maneuvers that the spacecraft will perform in the asteroid's low-gravity environment. The animations are presented in chronological order.
